First post noob here =)

I'm trying to prepare all my resources and loading them into RMVXAce.
Here's how I am enlarging characters ripped from 8 or 16bit systems.

Am I doing this right? Can you suggests better processes?
I haven't gone into Tilesets yet but that's my next step. Any suggestions on what challenges I might face in Tilesets will be greatly appreciated.

Thank you!

1. I take the 8 or 16 bit ripped PNG to http://resize2mail.com/ and set it to resize 540 x 720. (Sometimes 1 resize is enough)
2. Save the file and repeat the process with the new file but resize to 450 x 600.
3. If the file was already in RMXP format then I use Game Character Hub BETA to convert it to RMVXAce. (When I use VXC converter, the png transparency layer is lost and white background is fused into 1 layer.)
4. Then I photoshop the edges, sharpen, move them in positions if they are facing the wrong way in sequences. (Up, Right, Left, Down)
5. Using Game Character Hub BETA again to place them in the right position in Png.
6. I load into the game and preview it.
