Awesome. Nice work! What about capitalizing T, B, and P or doing “small caps” (like in Microsoft Word where it is all caps but the first letter of each word is just a little bigger)? Also, how about making the character look more like the characters of Nick Gaetano? Perhaps by losing the shielded face? Making the body sleeker and less cartoonish while still keeping him well-built (primarily the upper half... the lower half looks pretty good except the feet could use a little work)? Here is a link that may help… not saying it’s perfect but it shows the ‘Mercury Head’ without it being shielded:
