Nice job for your first. The blade looks nice with nice lines and proportions. You did a good job lining your spacers and handle up with the ricasso of your blade.
The handle looks a little straight and a little too round, at the butt end especially. But it doesn't look uncomfortable. Probably feels pretty good in hand.
Personally I think a guard has always been much more useful at protecting its own user's hand from slipping up onto the blade. I'm not saying a guard has never been created for catching an opponents blade or one was never used that way, but I think a LOT of that is fairy tale and wishful thinking at best.
Plus, I don't see that knife as much of a true 'fighter'.
The guard is too long, especially the upper quillion, in my opinion. Your total guard length is almost equal to total handle length. That's long.
I also don't care for wood on wood spacers, though there have been a few exceptions. This is not one of them.

The two woods on this piece don't compliment each other well and clash, to my eye. This is my own personal taste here so it doesn't hold much weight as a critique.
The hamon looks like it's there, looks like you got the back part of the cutting edge hardened and that's good. If a hamon is a failed attempt, the rear part of the edge is usually where it gets missed. But it looks like you did good there.
Good knife for a first. Make many more. Good for you for asking for honest critique. I don't think a maker should ever be past the point of critique. I know I still ask for it and welcome it on my knives.
