Practice makes progress!!!
We all have to start somewhere. It sounds like you may be too critical of your own work. Most of us are!
The best judge is using the "3 foot rule". Stand back 3 ft and if it looks good, it IS good! There is also the rule about a man on a galloping horseback, if he can't see the mistake, it is not there! :)
Seriously, be proud of what you have accomplished! Know that each piece will show some progress and move on. Be happy you have completed your project!!!
Post a pic so we can tell you what a good job you did!!
