Happy late birthday !!
Nice universe , a little bit strange but funny too, an interesting mix in my opinion ^^
About 1# Really interesting contrast , a strange creature , like a mutant or something but you
throw it in a funny background xD he make me laugh like : Ohhh Yeaaah I'm the king of the dancefloor xD (that was my first though when i saw it ).
2# I liked the Shadow effect , and you did well in my opinion on the shady part, reminds me of old pictures , like a portrait who where discovered years ago. (the caracter is a manga caracter isn't it ? )
3# The creature is really nice ^^ You seem to add more details on his body that on your first
However, Sometimes a simple background is better than a generic , you should try to just do a simple background but with you own style , i'm sure this should be better !
4# Hahaha i recognized him directly ! Nice Vel'Koz ^^ Same comment about background ! just do it simple but on your own style !
5# This one is really cool ! , Nice Style (you did very well to counterbalance your background gap by filling with your art ) I really like the mix between creature , and the fairly realistic human aspect, tooth aren't easy to draw in my opinion and you did it well ! I like the way you do diversity of creatures and emotion on their face. This one is my favorite, he reminds me a game i really liked : The Binding of Isaac. I think you find your own style with this, a strange mix of realistic , darkside and emotional.
A contrast with Funny thing like the #1 could be awesome too !
6# According to @SirLegendary the insect reminds me of kha zix too ! I really liked the "Are you the tooth fairy ?" joke , Nice work !
7# Creepy one xD like a IA dolphin, Nice job on the mechanical parts like cog , Fin ...
Simple background but he fit good with your artwork !
8# In my opinion he's better than the other who was great ^^ , i like the mystical aura , main eye is really cool too ^^ good work on shade too !
9# Really nice work on the hand made hands ! They reminds me of picture i saw in biology books ^^ , Again it's hard in my opinion to draw muscle and stuff like that and you do it well !!
In conclusion : Great job !!! I would like to see the next drawing you will make ^.^ !
Hoping my thoughts will help you in someway and have fun !!
P:S Really nice Kha'zix vs Vel'koz drawing and true xD your macho heimerding is really creepy xD. I think it's not in this nature to do Sports xD !
