This is a really good piece! Your style is progressively becoming more organic which is a good thing in my opinion
Are you contemplating trying to draw a complete scene one of these days (background and all)? I think that's something you should explore next which would help you improve even further! Just a suggestion of course.
Yes...thats like the big thing i have to tackle...i am a vision kind of guy...wich means i useally have a image instandly in my mind soi get frustrated when i cant make it reality.
Thats why scenes make me crazy because i cant make everything in a picture good enough to call it done...the problem of to many options :/
