Really nice lineart. For a phoenix design to go without colors is kinda strange. How about at least some accents of color here and there ? I think it would improve the design. Please check my Kraken shirt: [link]
Thanks for the feedback I know what you mean. I wanted to put colour in my design but it wasn't really working with the line work i had. I also thought i may already have over 5 shades of grey in the drawing so adding colour would be really pushing it.
