the photographer is Elena Serebryakova. in the future if you have to do more of these duplication assignments, even if you do not know the photographer to credit, please write in the description that it is an image drawn entirely from photographic evidence (esp. if its a single photo like this case). also, while ng makes posting links directly unclickable - here is an english web profile she has for said image.
I downloaded the .psd file and checked it out, just out of curiousity. No offense but I think your claim that you haven't "doctored the original" is a blatant lie, as for one: the photo is included in the file. You also even have a layer called "Lineart copy", which is basically an outlined version of the photo, the snowflakes are drawn right on top of the original ones with some minor additions and that blue "background" layer seems added afterwards to further deny any sort of copying. That's pretty cheap man. However, you still did a great job with the colors, the actual painting job is done quite well. It would simply be more impressive if you painted this either completely freely or just by LOOKING at the reference photo. That, however, takes much skill.
These are all accusations based on my personal impression of your .psd file though. It just seems very fishy to me. I still give you 3 stars for the end result, because as I said you did a great job coloring it while being able to maintain a realistic look.
I agree with the many comments below.
But I think you deserve some credit for your time/
If this was an actual drawing, it would've been cool.
I'm a photo editor myself, but this is hardly anything to toot a horn at, anyone could easily photoshop an image to make it look like a painting (I've been doing it since I was seven, actually...); I don't think it's fair for this to be on the front page, or even for your class to give you a remotely decent score (let's say your in photo editing class, or something). Looking at the original picture, the original is already edited to the max (or at least taken with a kickass camera) so there's nothing you could do to improve the picture or not. This is just cheap rip off for attention, even if you do credit the artist or not.
I could take this very picture of yours and gray scale it in black and white, now, should I get a good grade for that in my class, or even a front page?
I have to disagree with many of the reviewers before me. While your skill is decent, re-drawing somebody else work should not be praised, and it's definitely no front page material.
What do you try to achieve with this piece?
Was your goal to be as close to the original photo? If so, then you could do it effortlessly by copy and paste, but then that would be stealing. Even if you have done a perfect job of recreating the photo, it's still meaningless as the color and composition were all belongs to the original artist. If your goal is to showcase the process of copying other people's work, then you need to show that in some other forms such as a video of you drawing it.
If your goal is not to be as close to the original, then what personal touch have you done to it? To make it look like a painting? Well, that can be easily done with some Photoshop effects. If this is just an exercise or a practice, then it shouldn't be here, the art portal is for people to showcase their completed works.
I give you half star for your effort and time spent, but you need to work on something original, create something with your own fresh idea.
