Ok sorry for the wait. Ok here are the results!
Theme 1:
1st place:She has an amazing background. I really love her design with the contrasting colours and being asymmetrical helps you see the crazy. I like the close attention to detail, in the eyes the pupils are different. This is awesome!!
2nd place:
I love the clothes!! Fleshy dress is beautiful and the psycho vibe is strong and the lining is beautiful.
3rd place:
I really like the design, making only the eyes colourful is a unique but strong technique. The mask is also interesting, this reminds me of Tokyo Ghoul!!
Theme 2:
This was the only entry. I like the pasting of images, however, this doesn't look like you digitally drew everything. This is art but I would love it if next time you could do it yourself. Sorry if you did it just doesn't appear that way.
Side challenge
Only entry but this definitely is first place material. The close attention to shading makes this peace so beautiful. You should be so proud of this amazing art!!
