I just like to hear other people opinions and I might change her eyes and ears.thanks for the tip!

Feel free to surprise me on the image.

Hmm, design-wise, I wouldn't have made her eyes as orange as they are. If you wanted to make her look like a fair mix between her parents, make her eyes Jenna-brown with light yellow scleras. But you could make her eyes brighter yellow with black scleras like Aniu, which would really pop out on her design. Another note, her Balto-brown ears don't stick out too much against her fur color. I'd darken them just to avoid mistakes and such. I do like her ruddy-red coloring, though I would make her undercoat just a slight bit lighter to go along with the design as it would be easier to portray.
That's just some ideas though, the design is fine as it is and you of course don't need to take my advice and make edits.

any suggestions on her i should work on and i am working on your trade now. do you have a specific image you want Heidi to be rendered in?

As I am one for more complex tastes, to me, she is a simply-designed character. But simplicity is also a form of beauty. I really love her forehead marking though. She could also easily fit in with the Balto Universe, so that works.

All in all, she does have a nice design, quite pleasing to the eye.

omg she is adorable!do you like her design?
