G1 Guzzle

Getting down to it, congrats on Guzzle being the first ever transformer you own, but as for the art of him, i'll break it down to three things

The Good: Posing is phenomenal, and i love the added detail of the smoke coming out of the gun barrel. The auto-bot symbol in the top left corner is a nice touch, not sure if it's needed in my opinion, but it is indeed a nice touch.

The Bad: From the looks of all this, i'm going to go on a limb and say that you used a scanner to upload this. Don't get me wrong, i'm not knocking the use of scanners or anything, you use what you need to upload your awesome work. However, the contrasting colors against the white paper seem to darken the overall figure you've made, and while the details are clearly seen, it's just very slightly hard on the eyes to view the overall piece.

What Can Be Edited: A background to the figure would cut back the contrast, depending on the scenery and colors you use. If you're not up for adding backgrounds, you could try to lighten up the colors just a bit, again, to cut back the contrast a bit.
