Not bad for a first font, love the R and S. Try to make diagonal lines as thick as horizontal and vertical lines, X, V, M and N look a bit odd when compared to the rest. It seems to be a common beginner's issue, but practice with the bricks is the only solution, keep it up.

For help with diagonal thickness, see this tutorial.

You could use the irregular thickness to your advantage though, and make a more unique font. You already have some unusual glyphs which I like, such as 4.

A good start :) 10/10

I agree that consistency of stroke width is important. It gives a better balance to a design and makes it more legible.
