That's not a bad photo at all! However, it's a little 'over-exposed' for my tastes (where the sky becomes white, and everything else becomes a little washed-out). Is this a print or a slide? If it's a print, I suggest getting a reprint and scanning it that way, because they can correct those sorts of things... (providing you don't over or under expose by say, more than 2 stops...!)
With a little practice, you'll get the hang of it... you're not far off!
What other people think of you is none of your business!
