Thanks guys. Wish I could take credit for the UK shaped cloud - that was just good luck!
This us only the second challenge I've entered - still pretty new to the photography game and I'm still shooting with a kit lens until I can save up for a better one! So I'm pretty happy with this result.
Nice leading lines. Centered composition works well. Have you tried one with the rule of thirds?
Has anymone else noticed that the central cloud looks like Britain?
