First one is Ninth Wave by Ivan Aivazovsky. I like it because he did really impressive job on those waves.
I tried to stick to 1h time limit so result is sketchy and lacks detail. Should I work more on next pieces?
Things I have noticed:
-balance between detailed waves and even and slightly detailed sky
-waves create dynamic composition due to their angular position and shape
-variety between shadows on wave bottom and top of another wave
- strokes on wave surface along their direction
-emphasis on water detail - refugees are somewhat detailed but are kind of supressed by sparks on the surface and overall sea detail
Nice start. the sky is a little darker than the original. watch for that.
Be sure that you are keeping a close eye on your edges. Note where the sharpest sharpest sharps and softest soft edges are and use them as guideposts/landmarks for the rests of the edges in the image. Edges are important to space, form, and focal areas, so getting those in there will help the piece a lot. Once you do, you will see quality improve a lot. Keep up the good work. -jm
each will be different depending on complexity. another 15 minutes on the one above would probably get you to the level you need to be...catching things like the way the sky has a certain glow to it around the moon or the crispness of edges on the front waves. take as much time as you feel you need. speed will come.
