Very nice work. Simple design, nice lines.
Couple recommendations, since you are asking (i.e. thread prefix at the time of my reading this post is "Recommendations?"), and these are just my opinion:
I'm a fan of more taper in the tip profile, since it is better a piercing, which is a dagger's job in life, typically.
I prefer scales that cover the guard for ergonomic and safety reasons, though I have made them both ways, for various reasons.
With a dagger, I like to make pancake sheaths, because visually, they better highlight the knife's symmetry, and functionally they better accommodate the double edge.
What you've got there is very good, and you should feel a sense of accomplishment for making it, especially if you are new to knife making.
