He looks like a dog I lost a few years ago, his name was blue. He looked exactly like this i mean, one of his ears was flopped, the color, even the eyes. I think you should name him Blue it fits him to me. ^^
If you want to go double name consider MudSlide or LastCall but a good name would be Bullet personally I would go with Fate, and if you want to see a dog with blue eyes to help you out, i have a few in my gallery, but by the looks of it you have it perfect love it!
I do love the colors of this character, and they look especially nice in gouache. I am particularly keen on the color gradation in the shoulder (it looks like it goes from white to yellow, rust, and then the darker brown). I am very curious to see where you'll take your gouache paintings as you get more practice.
You might find that you have some more control of the paint if you let your brush be a little more dry. It looks like you're using a lot of water and a really wet brush. If that's your intent go with it, but you will get a little more finesse if you wipe your brush a bit more after dipping it.
You have some nice blending and wet-in-wet effects going on that lay a nice foundation to be built on.
U know... This looks very much like one of my friends breedingwork... My dog Sirppi is his father and smooth collie Lara his mother. Look at his picture! Just like this character of yours! Awesomely cool! Here is Kossu (now his another ear is up, if u klick the picture, you will see more): [link]
Here is more different puppies from that same litter: Female called Kina: [link] Male called Colhu: [link]
This guy looks amazing! I love the texturing, and how luminous the eyes are! He somewhat resembles [link] of my art, though yours looks so beautiful! Keep it up! If I may, could I reccomend a name for him? I was thinking cappuccino, but that might be a bit too long. Haha!
