Your spraying works pretty well.

I dont want them be too bright that looks badly.
Not that my pictures are perfect

, really not. But I think what cheng means is that you might consider to add some more contrast to your pictures. I took three of my favourites, cut the surrounding whitespace before and used the automatic contrast correction of Paint.Net which is freely available. (Of course with this tool further changes can be made, too.)
If I went off topic too far, i will remove this post instantly on notification.

And I promise not to complain again should you wish to keep your special stylistic feature.

And please send the padre over as soon as possible. There are a few scoundrels around here that deserve a decent sermon.
