Congratulations on your first blade!
As Kev said, if you haven't hardened it yet, pin holes are in order. But you asked for feedback and here goes:
The good:
Excellent proportions. That is a really nice design. It looks a wee bit tall in the handle, but since I can't really gauge the size from the pics it may be just fine. Putting a handle on a tang totally changes the feel. If the tang feels "just right" before scales you can guarantee it will be too big after you put scales on it. However, it's a matter of personal preference and I'm just going by a picture.
Your bevels look pretty dang flat. That's no small feat on a first knife.
Your centerlines look good. Great attention to detail.
The areas to improve:
Your plunge lines. Again, it's a first knife and having less than perfect plunge lines is to be expected. In the beginning it's best to finish your plunge lines by hand rather than try to chase your lines back and forth on each side trying to get them to match. You did get them to be pretty even at the edge, which is great. Now practice on getting them straight. A file guide can work wonders here. Also, the grinder is merciless on plunge lines. You may discover that a file is your best friend on your first ten knives.
Your plunge lines also break through the top at the spine. This is generally a no-no. It's an aesthetic thing and the knife is none the worse for wear if your plunge lines touch the spine. On future knives, though, stop shy of the spine. This can be fixed after the fact. Lay the knife on the flat platen and grind lengthwise. This will thin your knife a tiny bit, but it will also restore some flat at the spine. Just be careful because it will also make your plunge lines a little wonky if you aren't careful.
Overall: a very nice effort on your first knife!
