I was wondering how much my art was worth and what tier it belongs in i and what i need to work on.Here are the most recent peices.

i'd say tier 3 for now, the images aren't very complex, but with a little more practice and learning to manip easier, you could do tier 2 at some point. The second image is really pretty, something like that could be an easy 30-45k

The same for the 3rd one, very pretty, 30-45k

The lighting is very nice in the second one, but the lighting of the horse doesn't match the background in the third one. I'd say start in Tier 3, maybe about 20-30k for now. Start out and see how much demand there is for pieces at that price and you can adjust if necessary. I'd say you should work on manes and tails, and trying to make the horse the focal point of the image so it fits into the background but is still the main focus (techniques like blurring the background, adjusting saturation and contrast, etc.)

I'd say low tier 2 actually. Around 40k-50k per piece :)
