Rait - All of your letters the same width and height. Maybe draw a rectangle as a guide. Every bar needs to be the same width. Look at the left leg of the R. It's twice as fat as the T. Should it be? No connection on the A and I, and if you're drawing upper case letters, do an upper case I as well.
Take off the extensions on the T.
Look at your keyboard. Block letters are good to practice, but keyboard letters are not exactly block letters.
You basically need to work on keeping everything straight and consistent.
