Obviously, Oscar, you have no idea about what a good photograph has to be:
1. a pillar, of itself, holds no interest to third parties;
2. you have allowed important shadows to go below an acceptable value;
3. your monitor is obviously not propely calibrated;
4. the total lack of a strong, definitively blue sky makes the image look ridiculous.
But I can help you!
I have just published a new guide - a guide to end all guides - that is available by direct purchase from me. I don't use shops because I don't want my new best friends wasting precious learning time going shopping!
Just post a blank cheque to the address I shall give you via PM. (I ask for it to be blank so that I can save you money by giving the very best exchange rate at the moment of purchase! Every little bit helps!)
Expectantly yours -
Garry.
