At PapaZola: Lol, what? What do you mean "from Loouuiiss"? I didn't think JIGSGFX is the same person as Loouuiiss... and I doubt it =/. Did you mean Loouuiiss had a similar design? Well anyways, you guys kind of claimed it as your own work lol based on the website link you provided. Best not to do that next time as JIGSGFX has wanted people to keep his credits for the 2 free designs he released previously. Mention that you guys re-designed it or something (though, yours seemed almost exactly the same altogether).
At NekoChang: It's good that you're not claiming it as your own work, though there are parts that are pratically the same in terms of the layout, and you are doing this as a paid service... Though, it is better that you clarified that it wasn't your intention to use a similar design and that it was your client's request. A good job with the re-design, but it would be nice if you can re-arrange some stuff and perhaps mention in the footer design where the work was inspired from (re-designs do not necessarily have to have the exact layout, but meh, it's up to you in the end, and you are bound to have situations when people criticize you for using practically the same layout as someone else's). At least the top part of your design is completely different =D. It would be best to mention the source that you are re-designing from next time in the thread that you are showing off your works from. A similar situation happened to NibiDesigns, so it's just to warn you XD.
Suggestions: It's a good design altogether. If your client wants, you can add a WoE status (to say whether WoE is on or off currently) and maybe add a Peak Online indicator. Perhaps add a ranking button and a database button/selection box if your client wants those Flux functions (the Useful Links box can be edited for these, though it would be nice to spice up the website more and not use the exact 4 buttons layout on the left side). The background image is pretty, but personally, the bottom (footer area) isn't as good due to the murky colours. Maybe another picture can be used there, but it is not necessary. A donation shop rotation slider can be included if wanted (or add a donation/item shop button somewhere). Would love to see more of your future designs <3! Keep up the good work!
