Hey,
If you’re just starting out, don’t bother with watermarks and even the black border. It’s just very unnecessary. No one wants to see a colourful watermark and a scratchy black border.
Richard is right when he said “The photo it’s self is out of focus as the car is quite soft and there isn’t much sense of movement also the framing isn’t too nice”, this is just technique and style. When you learn more and more, your technique and style will get better. Just, keep it simple and easy on the eyes!
Not to show you up or anything, but here is an example of my day at mondello. I hope this will help you in the future
