So, about my profile, I think my main problem is that I didn't want to cram it full of text, but now that I see some of the pages here more, I don't think I have to worry about it too much. If at all possible, could you maybe give me some pointers as to how to fix it? Still learning the ropes as I haven't been too active here in a while and haven't had time to learn much.
for first thing you need to give explanatons for why his physical statistics are the way the are
for second thing, you should list the sub-powers of abilities that your character has
Shapeshifting: A common Astroidian ability. He can rearrange atoms in his body to take any shape. He can perfectly replicate anything he wants, down to its color and even atomic structure. He can even create fully functioning organs if he wants. He can grow to a maximum of planetary size and a minimum of atomic size
another thing that you should change is that you need to add a Key at either the bottom or top of the profile to note of the different versions of the character, instead of putting the names of the forms in the Tier section.
Key: Base Form | Second Form | Third Form | Ultimate Form) | Doomsday Form

About the regen, regenerating from something as small as a grain of sand is Mid-High, not Low-High.
Another thing that you may want to change is
Standard Equipment: Nothing except his own natural abilities
Standard Equipment: None
but that's more just personal preference
One last thing, you may want to add some Resistances to the profile, which is what is given to a character when they aren't affect by a power.
