Miss hit and miss -_-

Ye, I upload something once a month when it's good. Why?

It's not about laziness, it's just I'd like to change a bit my point of view, giving some more "peaceful" deviations . But every time I work on something, also if my concept has beautiful colors and bright lights, don't know why working on it uhm..  At the end, it becomes really dark, and this happens everytime.

I hope someone reading this post can give me some tips to 'evolve' my way to work.

I'm really tired to look at my designs and tell ''Oh my, once again so dark?"  !

Please, could someone give me some advices? I'm pretty sure I'm not the only one in this vicious circle.

If you can, please, help me to look through it (guys, don't forget we are near Christmas..think to Santa's..do your good action ).

Every comment would be appreciated. 

HALP!  

 Thank you for caring
