HI DeJynes
First, I think your image is really cool and clearly you have quite a bit of creative capabilities. I'm impressed!
Photoshop is not the easiest program to learn so here are some thoughts for the future and also a temporary stopgap "possible" solution for you image.
1) Running on such an old version of Photoshop can be pretty tough to get help as many have moved on from there. That said, not everyone can move on from the old versions. Photoshop archives many of the older version of Photoshop help files, that archive only goes back to CS3 yet that might get you closer to the version you are running: https://helpx.adobe.com/photoshop/archive.html
2) You are processing in CMYK color mode. Not all filters work in that mode and the majority of those on the forum work in RGB color mode. Unless you have a strong reason to be in CMYK, I suggest you use RGB color mode and also in the color space of sRGB. More people can help with RGB mode issues and there are typically fewer color related issues if you start with sRGB
3) When loading your PSD file it looked better on my version of PS that what you originally posted. Not sure what is up with that yet not too bad for the pixel dimensions you started with.
4) I agree with IamSams recomendation that a) starting with more pixels is very key to a better overall image and b) for the more pristine results, using Shapes and paths are more accurate. Note that when you add items such as strokes in Layer Styles with low resolution images, not only are the original concentric circles going to be more pixelated, that gets even worse with the Layer Styles which add to the boundaries of those rough edges. Starting with more pixels may be sufficient and if not, using Shapes and Paths will make it even smoother.
You asked a good question about needed to start over in this image. That is a judgement call yet you could create shapes and apply the same Layer effects to those to get rid of some of the jagged edges and wobbly color glow effects.
A stopgap is to use a program that can enlarge images and provide decent results. I have used Gigapixel AI from Topaz and for some images it does a pretty good job. I increased your base image by 4x in size. I saved it as a TIFF file in 16 bit mode and am sharing it at this dropbox link. I also converted the image to RGB mode in sRGB color space:
https://www.dropbox.com/s/k8uwnmertfn8gw8/EmergenceOfANewDawn-1-enlarged.tiff?dl=0
Below is that dropbox image converted to JPEG and reduced in size to 2000x2000 pixels for viewing on this forum (again RGB color mode in sRGB color space)
Hope this helps you out some
