How is it that you have Indigo 6.5 to begin with, wondering why you didn't buy iClone 7? 
Because now you are asking about getting better visuals, and everything you want, and will want, is in iC7.
Who, or what, told you/suggested, that you buy iC6 now, as opposed to iC7?

Hi thank you for your suggestion, I had Iclone 6 before 7 came out, I have been practicing with 6 for some time now but I never really practiced rendering that much until I started making some few projects.

Hi, I really wish to thank you all for you suggestions, they have really help me a lot to get my rendering better than before, I will like to follow you all on your YouTube channels if any so I can at least see what you guys are doing so I could also learn some more.
I will also like to share my works so that you guys can help me check it up and advice me on what to do and not to do.
Am also making arrangements for Iclone 7.2 as I have checked and seen what you guys are talking about. Thanks to Iclone cause I don't know anything before but now I can fulfil my long term dreams on 3D animations.
