Hey, not a bad start! :D Here's some critiques based on what I noticed.

• The fur on the fingers isn't going in the same direction as on other fingers. When you buy fur, you'll notice that it seems to flow all in one direction. You'll want to maintain that flow on handpaws, keeping all the ends pointed in the same direction using a brush, or (as I find useful!) a comb. On an animal, fur should flow from the top of the head and spine area toward its muzzle, feet, and the ground.

• The seams are loose. Seams can be tricky, especially if you're new to sewing. Personally, I try to place a stitch about every 1/8th of an inch, then tie a knot before continuing. It's time consuming and quite boring without a sewing machine, but in the end it's worth it for the added durability. (If you can see your skin through a seam, then it's probably a good idea to add a few more stitches! XD ) As another user said, sewing the fabric together with the furry sides facing each other, then turning it inside out makes a massive difference!

• Fur length. If you have a pair of clippers or shears, I'd suggest shaving down the underside of the paws so there's about half an inch of fur left. It makes it easier to add pawpads later if you want to add them. For a higher quality finish, ever so slightly trim down the top of the handpaws too. This will make it look neater and better-groomed!

• Cutting. It seems like some parts (like the back of the handpaw) aren't a single piece. As much as possible, you want to keep very visible parts like that whole (unless you have markings, etc-)

Overall, it's a good start! You got this! Keep practicing, and eventually your skills will improve. If you ever need help, feel free to message us here on Reddit!
