Making Banners using Photoshop

I started learning how to use photoshop recently. It was a bit complicated at first but I'm getting used to it slowly. At school we needed to make a banner for our blog. So I started fooling around with brushes and colours and I ended up with this kind of banner:

To be totally honest I am not impressed with it and the colours are not my style, including the type of text I used. Thankfully it was a just a first try. I wanted to share it with all of you and maybe get some opinions. I obviously didn't want that kind of banner on my blog so I decided to make another one, and I must say I really like this one!

Feel free to comment!

I will be posting more banners shortly!
