First art:
Nice, I like how youve done the colors, the negative though is pikachu, eyes are big and quite bad in the body part.. The eyes of the man is rather attractive!! ^^
2nd art:
Girlish! I love the flow and the colors of the hair. You are great in drawing hands.. really..
3rd art:
Okay.. This one would be the best among the three, bloody!! I find the background.. amusing? hehe, kidding!! really great..!!

All in all rating for my opinion.. 7/10 n_n
Keep it up!
