They look great. I'm a big fan of that type of rough shading. Thumbs up from me.
I've been working on these all morning/afternoon and figured I'd post my progress. I'm planning on doing at least twice this many in total and then will work on doing a colorized version. I'm pretty happy with how they're turning out so far.
Its fun to do such Mountains, I have draw them for 2 Days too. It gives the composition a nice touch, but your are right you needs a lot of them to dont have doubles appera to near to each other.
I think this is probably enough mountains for now. I might go back and re-do some of them that I'm less satisfied with.
I'm also going to work on some city symbols and trees to fit with the same style.
Do we get to name the different mountains, so the brushes have silly names?
Also made up a brush set after I colored the mountains...thought someone could maybe also use some shaded mountains. As with the other set, feel free to use for whatever you want.
Wonderful stuff, man. I'm sure lots of people will be using these. And it's great to see you giving to the community with your usage policy.
Hopefully the rep God will let me have at thee.
