Hi HffRibeiro welcome on our forum also from me.
I have see that you don't have used post production.... i have tried to do it with GIMP, 2 min of post production and this is the immage tha i have created.
Is only a test for me that from some days i have make chois to pass my immage with post production. in this way you can see the difference betwins my imm. and your one.
Omg good work
PS sorry for my bad english
