Wondering if I were to go along these lines from my current build would I be underpowered at all in the later stages of the game or would I actually end up just fine to handle any situation? The reason I've asked is at the minute I'm playing a sneak based archer build and I'm finding that going into a dungeon and clearing it out whilst rarely encountering any danger as fun as it may be it just gets slightly boring. Alongside sneak and archery i've levelled up one handed, block, light-armor and smithing. I'm planning on having an all rounded character towards end game with the option of using sneak and achery to clear out if need be but also able to go toe to toe with most enemies if needed in close quarters combat.

My current skills and perks are;

Race; Nord
Level; 25

Archery 62

Overdraw (3/5)
critical shot (1/5)
Eagle eye
Power shot

One handed 60

Armsman (2/5)
Fighting stance
Savage strike

Light armor 57

Agile defender (1/5)
Custom Fit
unhindered

Sneak 53

Stealth (1/5)
Backstab
deadly aim
Muffled movement
light foot

Block 35

Shield wall (1/5)
Deflect arrows

Smithing 55

Steel smithing
Elven smithing
Dwarven smithing
Orcish smithing

now these may be under leveled already I'm not too sure but I'm finding using just sneak + archery is satisfying but as I've mentioned earlier quite boring too. I'm trying to smith deadric weaponary and dragon armor when the time comes and all that added armor i'd end up smithing just seems like it'd be a waste if i were to just leave it rotting in a chest or selling off in a shop. My main concern is if I invest a couple of perks in Heavy armor and carry my proggression on as it is would I find myself later in the game struggling to keep up with anything thats thrown my way or would I still be able to hold my own? I'm also looking to be self sufficient in terms of creating weaponary/armors but I don't plan on branching into alchemy unless I have a few perks left over towards the end game.
