Torch21 - keep going man, those bars in your alphabet are looking proper, although the y is looking a bit funky
Sureisshitty - I think your piece could benefit by having that bottom bend of the S come down a bit further and the middle of the E pop out bit more, looks good though
ARA - that fuck the police piece is real nice, the only issue is the k, the bottom leg should be converging with top leg when it meets the backbone, look at the K in torch's alphabet, also try some thicker 3D, IMO it will look way better that poodle thin 3d
Color killer - those are looking fresh, no crits for you, keep doing what your doing then proceed to advance your style when you feel comfortable.
