Hello! This is my first ever manip and I must say, I'm very proud.

What I did:

Changed horse color from chestnut to Dapple Grey Tobiano

Repainted mane/tail and eye

Changed background lighting

Shaded horse

Added fireflies

Can I get some opinions on the tier I should be in, and what to price this piece as? (Planning to auction)

Thank you!

Lighting looks good, and good job on the tobi.

I would work on hair, the highlights are a bit abrupt and linear, looks less natural. The face could use more definition, not sure if that's just how the stock was or if you used too much smudge.

I would also work on adding shadow/highlight to the body, and make sure it's accurate to where the light is coming from.

As for the shadow, on an image like this were the background is water, try taking a png of just the horse, lowering the opacity & blurring a touch, and use that as a reflection

Overall, it is absolutely amazing for a first manip!!

I would probably put you mid T3 to get started and price around 15-20k for a set and 30k for a horse avi.

Yeah I'd definitely start off tier 3. Pricing maybe 10-15k for a horse avi and 20-25k for sets. For that specific avi, I'd say auction it with the SB of 10k and rather than put an AB, set a specific end date. That will get the best out of your piece, and tell you just how much people are willing to pay for your manips!

Thank you! I will keep in mind the hair and reflection tips ^^
