This was kind of a pleasure to zoom into. I would have loved to see an even amount of detail throughout, though. The keyboard clearly doesn't have the same level of detail as that beautifully smooth tablet, it makes me wonder if you painted over an existing picture and added details like the crumpled paper later. I feel like the wads of paper and the images on the screen really ruin the effect here because you haven't put the same amount of effort.
There's a strange uncanny feeling to this picture, and I can't quite put my finger on it. It may be the perspective lines not lining up (back of the table) or the computer monitor and stand being oddly separated. It may be one of those monitors attached to a crane in the back, but the viewer won't know that from this angle, so it looks strange.
I also feel like the Spiderman and Spongebob was a poor choice, they are very jarring to see included. It may have something to do with the color choice being that bright cyan against those harsh yellows and reds. I think it would have been interesting to see more of an interaction with the environment and more of a blending of the cartoon characters into the real world. Just throwing some ideas out here, for example, there could be webs shooting out from Spiderman's wrists, or the use of overlapping on Spongebob's finger to make it seem like it's protruding from the screen. Simply placing his finger in front of the earphone cord could help here.
I also feel like this area could have benefited strongly from using a more realistic texture and painting technique on the portions of the figures that are outside the screen, especially to incorporate the mood and color tone of the room on them.
Overall, I feel like some portions of this are really well done, but I would have liked to see all that energy applied everywhere.

I legit thought it was a picture until I read the description!!

this is so cool! i have that exact same tablet lol

Omg I thought the background was a photo, nice job!

The background looks so realistic. Great job!
