A LightningxStarfire moment

These are things I know I need to work on. I would love to hear more advice though.<br />
<br />
1: The lineart doesn't really match the coloring.<br />
2: The characters look a little too posed. I shouldn't have had them looking directly at the viewer.<br />
3: Starfire looks too manly.<br />
4: Lightning's right shoulder/upperarm seems rather odd.<br />
5: Lightning should be shorter and isn't that bulky, that just happens to be how I make men.<br />
6: The coloring in the background grass should have matched the other coloring.<br />
7: Lightning's hand looks out of shape.<br />
8: Starfire's neck looks too flat and straight.<br />
9: I need to work on shading my metal. It has no obvious difference from the cloth.<br />
10: The sky looks too flat.<br />
<br />
Okay, those are the things I know I need to work on. If you have any different critque, I would love to hear it. I like knowing what I need to work on.
