Ello, great thread!
This is a 1.5 hour speed paint for a client but I want to go back into it one more time based on forum crits. Feedback and hard crits encouraged! 
A) Quick application of colour and basic mountain shape (I used the polygon select tool for this) in photoshop.

B) Imported it into ArtRage2 and put in some textured line work. Really easy to do this, very nice and intuitive program.

C) Back in photoshop now, adding some soft clouds trying to pull directional focus with my strokes.

D) On a new layer I add some block shapes for the foreground, this will be a bridge leading to a tower. I used the polygon select tool again for most of this.

E) Started adding in details - looking back I should have defined depth more by making the tower lighter.

F) I had to add in another tower for this job - why didn’t they tell me at the start!? So I did that really quickly but you can see how much further away it looks just by making it lighter or allowing some of the background colours fade over the top.

G) Final touches. I’m pretty happy but still with problems:
The mountain looks too high in contrast, needs to fade out more and this is ruining the composition - the tower and the mountain seem to be fighting for focal attention.
Have I overdone that bloom on the left there? Is bloom the new lens flare? …NO! …NOOOoooo!
I’m not so good at perspective and I didn’t measure up for this one, so not sure if that feels right.
Is it too dark?

thanks for reading.
