@rabidbaboy: Yes, freedom is one of the feelings I tried to capture. Glad you like it

@Terley: Thank you

you'll probably enjoy my next update it is still smooth but has a much organic feeling, I think!
@Matriax: Thank you for the edit, even though it is a bit too drastic for the purposes of my picture - it gives it a too lively feeling

@VictoR: Well, the light is supposed to be the sun...guess I failed there

@Overkil: Well the point of the activity is to portray an emotion by the use of one hue/colour (not necessarily in an abstract way) so I'm not going to incorporate many (if any) hueshift in here. Thank you for the suggestion though.
A little explation of what I was trying to do here: as it has been noticed already, freedom is one of the words. Personally I find that easy to spot since birds in flight are the main representation for that. Apart from that, I tried to depict calmness/serenity, by the use of the blue-ish tone, and hope, with the representation of the light appearing in the midst of the grey clouds.
An update should come in few time (and since this has to be done by 10 pm...)
PS: snake posted as I was writing, thanks a lot for replying

do mean rim lights?
