I have done artistic graphics for nearly 5 years now, working with some professional work in between. Was on a professional crew where we were given a job and commissioned if our work was selected. I managed to collaborate with the lead designer to create things like album covers and logos etc. The site is called mycoastlife, and I quit shortly after because of school commitments.
I have also participated in graphics crews on forums such as planetrenders, gamerenders and my own individual battles with others in the same "league" as me on nationalsigleague. More recently on planetrenders (I am still in the crew but have not been so active as of late) I have co-created and lead a team of my own, organised battles and selected works that would have given us the best advantage on the battle side of things.
I have little experience with designing websites as a whole, however I do specialise in the smaller components such as banners, headers, logos, buttons etc. I can certainly create a decent looking website if it is needed, but as far as I understand, from reading your post, you're looking for someone to do some adjustments rather than re-make the whole website. I really think I would be the man for this job.
I can easily tweak colours, have a keen eye for detail and artistic merit (if something stands out too much, or it's colours do not complement the surrounding, I will fix it. I guess I'm just a perfectionist and won't be content till it looks right)
Lastly, any money I make off this will be used as I am less than 5 months away from completing my school life, and will have to move home to live on my own for university. The money will really help me out, but is certainly not the sole reason I would like to take up this job.
Please don't hesitate to contact me via PM, or if you have any enquiries about me, and what I do, feel free to message.
Thanks and looking forward to working with you
