Excuse me for stating something very obvious here, but you'll need to foot up much more cash than A$110 if you want all of that criteria in the artwork. Come on get real.

Hello there,
Thanks for your invitation. The brief says clearly this will be huge illustration. But it's not clear about the size or where you are gonna use it(Digital or Printed). If you can share technical details I might be able to try some sketches.

Thanks.

Hi. This is to be used primarily on the website. I would like it to look as realistic as possible.
Thanks

hi may I ask you something?

how large the design should be?
I see you want to use this on your website, but do you have a specific size in mind?
example (1080 X 720 pixels)

Hi,
Yes 1080 x 720 will be fine.
Thanks
