no, seriously, you have got nice drawing skills... why don't you use other drawing programs like PaintTool SAI and GIMP, etc.? Your drawings will be a lot better especially your lines will be cleaner and smoother.I just say that because i really like your drawings but you can be better. I like SAI more and i think it's very easy to use ^.^
Anyway beautiful work! I really like how Ren looks!
