i don't like this 2/5
Why not?
Constructive criticism plox.
Anyhow, X-Omg-X...
It's a tad simple (yes, I do realise it is supposed to be. Move icon, after all). For starting out, I would recommend you made something else than a move button. Something less plain. I think that you would learn a lot more from making (and then improving) an icon depicting something (else than an arrow, anyways). Make an item icon, some sort of object, with more interesting shapes and details, so you really get to practice your shading/highlighting. And by the way, colours aren't illegal, you know
As for this icon, I would give it a 2/5. It's a move icon, but it doesn't really look great. If you want to change the command buttons, you'd do it for one (or eventually more) out of three reasons:
1. You're making a map with an interely different theme than Warcraft III itself, so you need something to match your theme (and eventually your custom U.I, since you'd probably be using one of those as well if your theme really is that different)
2. You don't think Blizzard's red arrow-like command buttons fit Warcraft III, and you want to swap 'em out.
3. You think Blizzard's command buttons look like crap, and you want something better.
Now, I really don't see how useful this move command button is. It's just... All black, right?
And it really doesn't look any better than Blizzard's own command buttons. (My honest opinion says so, at least)
You should make it something more special. Either make a special themed Move icon, or improve this a hella lot, so that it's better than Blizzard's own.
Just read tutorials (there are some here at THW. I'd like to link some, but I cba right now), look at other icons, and work till perfection with some few icons rather than mass-producing a lot of mediocre ones. Another way to learn is to try to mimic some of Blizzard's icons. Or other people's icons. One of the best ways to learn is to mimic other's masterworks.
And I'm sorry if my critique of your icon seemed harsh and unsensitive. It's nothing personal. Just trying to help
With practice, I bet you could make some smashin' icons some time!
