YCH Batch #1 (1 available)

Finally trying my hand at this. Instead of an auction, the prices are set beforehand. First come, first serve!

As soon as this batch is exhausted and the finished art produced, this batch will be scrapped and a second one will be drawn.

The prices and details of approximate minimum dimensions are as follows:

A: 100 - bought by Ocean-Sky-12 (status: lining)
Description: a spyhopping headshot that will be scaled up to 500x500.
B: 200 - bought by Ninuturu (status: lining)
Description: a diving profile to be scaled up to 500x900.
C: 300 - bought by iiduh (status: lining)
Description: a full profile coloring that will be scaled up to 800x800.
D: 400
Description: a dual portrait of an orca and commerson's dolphin to be scaled up to 1000x700.

The linearts will be made available for critique before coloring. So don't mind the rough edges and funny anatomy here, I tend to fix that as I go.
The backgrounds will either be simple gradient colors, or some abstract mixing like these examples:


Keep in mind - thorough reference sheets are required! I would like the final products to be as accurate as possible.
Comment here if interested! Details can be discussed via notes.

Enjoy!
