the problem is, sketch-up does not provide editable shapes, therefore the Photoshop file is not really editable if you use sketch-up.
and in sketch-up you don't really have access to many functions that a good illustrating application provide, that's why your logos don't come out as polished as professional work

hello. @kiaazad, i'm done installing the Adobe Illustrator.
i will be using it now for the Open Arena logo, guess i will still using this logo, cause many of my graphic artist friends said it was a good concept and idea.
so im going to use AI to create this logo.
and thanks again for the suggestions and advise. ^_^

unfortunately your new design is not an improvement over the existing logo, if anything, it has gone in the opposite direction.
