I love your style man. Disturbing, unnusual, horrific, mutant looking things with psychedelic colors, and SHARPIES? You sir, are one talented son of a binocular being. ;)
Not only is it well drawn, but the use of markers is awesome. I always find markers unyielding myself. I can never seem to use them effectively, and I always end up accidentally marking over other sharpie marks, leading to an uneven tone.
So, rats off to you my good sir. I like it, and for some reason it reminds me of that mutant baby/tumor thing in Total Recall, if you've ever seen that film. Nicely done. If I ever record an album in the future and need a cover artist, I might contact you. I may be willing to pay you for it as well, but we'll see.
Anyways, good job. :)
