The writing is fantastic and so is the picture but maybe if you want more of a boom maybe you can out line the whole body and not just the head? But besides that it is wonderful and I love the details. I also love how you draw attention to the head in stead of just putting him in there and saying"yep this is him" you actually took time out and did that. I think that you have a lot of potential and you should experiment more with stuff that you wouldn't normally do.
I hope you can continue to put great art up such as this one.. you are an extremely talented artist.
