hmmm i think it is totally fine and a good start but what i think is kinda wierd/annoying (not sure what is the right word to use here) is the bluish/greenish color on the edges.

i think it fits and gives a shinier look when it is on the armor/cloths but i dont think it fits on the body skin. just wanted to point that out but it is up to u if u want to change it or not.

P.S is this girl from a game or anime or she is one of your creations?

you attempted something different, and you really succeeded at it! Not bad! :D

It's always a good idea to venture out of your comfort zone from time to time to improve your art.

Your lineart is still steady without use of the line tool, which is definitely a skill to be proud of.
The choice of colours/shading is nice and colourful and still manages to get the muscle details to be shown clearly.

I notice though that some of your colours and lines overlap or extend past in certain areas, and near Melandy's hip there a few floating lines. This was most likely part of the line art experiment to fit in with the painting theme, but if it wasn't intentional, simply going over and erasing those lines would correct that.

Anatomically speaking everything seems proportional, so other than some additional clean-up with this image I'd say you did a very good job. :)

With the brush tool you have a lot more control over line thickness and curving, just a little more attention and care is required to prevent the line-art from looking a bit messy.

That said, I'm still incredibly impressed at how fast your skills are improving.
Keep it up Boco! :P
