This looks awesome. I really like the thick linework. Is this going to be a tattoo?
The logo of this band is black and white, so why i would use a color?
Since this is a logo I think you should consider adding color and blocking the shading to make it printable. The photo angle is very distracting and skews the image.
This is a really nice drawing! The one thing that distracts me are the shadows on the spikes in the helmet. I don’t think they’re needed. Might be cliche, but cool if there were flames coming out of the eyes. Not sure if it would be too much or both though. Nice work!
