Judging from these enquiries, there seems to have been a few teething problems with this skin and for that I can only apologise. I've been involved with drawing for years and feel fairly competent with that but on the uploading side I'm a mere novice and obviously have got one or two bits out of sync. Thanks to all who have since sorted it for me one way or another. I promise I'll get better at it, hope it hasn't spoilt any enjoyment. I see there was mention of the size of file. As an explanation, I initially resample the 72dpi templates to 144 in order to have a bigger surface to work on and so increase the level of detail, hence the increase. Personally I haven't had any problems flying the skin and I only operate on a 'dinosaur' of a comupter with a slightly overclocked AMD 1.1 gig processor and an old Radeon 7200 graphics card.
Anyway many thanks for the feedback.
