Help me With the shading on this one, what would i add to make this one look better?

yeah i actually had it like that too look more you know cartoonish have it over exadurated but i guess it does look a little bit weird but also do u have any tilps on shading??

try using a softer/lighter color on the outlines that arent the primary figure outline, ie the outline of the muscles in the upper arm.  I would suggest continue shading as you're doing now, but make the shadows tighter and quicker to run off a slope or bump, such as from the underarm to the bycept.  If you are really having trouble shading, check out other peoples' works, you might sometimes notice a pattern, kind of like tweaked isometry, this helps me to shade most of the time.
